Yes, I have to brush Squishy pretty much every day or he will get matts, which is usually why I keep it cut. But Squishy is pretty friendly, they need to be socialized a lot so they will stay friendly, but eek eek eek goes for EVERYTHING Squishy screams at me if he doesn't have food, wants out of his cage, needs water.. he's a loudmouth and I'm pretty sure most Piggies are! But I think it's cute so I love it.
